Abstract
The utility model provides a gas bag nitrogen sealed sink which includes a sink and characterized in that the gas bag nitrogen sealed sink further comprises a nitrogen holding gas bag, nitrogen supplementing gas inletting pipeline, a gas passage which connects the sink and gas bag respectively. Wherein, the gas inletting pipe is provided with a valve. The utility model can reduce the consumption of nitrogen greatly and save operation expense.
Description
Technical field
The utility model relates to a kind of production unit of ultrapure water, particularly a kind of air bag nitrogen water shutoff groove.
Background technology
In the production of ultrapure water, enter tank for fear of outside air, and gases such as airborne oxygen and carbonic acid gas are soluble in water, reduce super pure water, need in ultrapure tank, to be provided with the nitrogen envelope.And nitrogen water shutoff groove of the prior art is to be made of reducing valve and exhaust water seal.When liquid level in the tank reduced, nitrogen pressure reduced in the tank, and nitrogen is injected in the tank by reducing valve, keeps the nitrogen pressure of setting; When liquid level in the tank rose, nitrogen pressure rose, and nitrogen is discharged in the air by the exhaust water seal.The critical defect that this nitrogen water shutoff groove exists is exactly: according to the usage quantity of back segment pure water, liquid level constantly changes in the ultrapure tank, and a large amount of nitrogen enter in the air, and the nitrogen consumption is big, thereby makes the working cost height.。
The utility model content
The purpose of this utility model is in order to overcome the defective of prior art, a kind of air bag nitrogen water shutoff groove to be provided, and it can solve the problem that nitrogen water shutoff groove nitrogen consumes, and can realize the approximate zero consumption of nitrogen.
The purpose of this utility model realizes by following technical proposals: air bag nitrogen water shutoff groove of the present utility model includes a tank, it is characterized in that it also includes one for the air bag that holds nitrogen, a gas pipeline that can this tank and this air bag be connected for the intake ducting that replenishes nitrogen and, this intake ducting is provided with a valve.
This intake ducting is arranged on this gas pipeline; Perhaps this intake ducting is arranged on this sink top or this intake ducting is arranged on this air bag.
This valve is a manually-operated gate.
Positive progressive effect of the present utility model is: the nitrogen of the utility model realization tank seals, but nitrogen can only not need interior a little nitrogen that replenishes of regularly past air bag get final product because of being discharged into air loss, can reduce the consumption of nitrogen greatly, saves working cost.
Description of drawings
Fig. 1 is the structural representation of the utility model air bag nitrogen water shutoff groove.
Embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
Embodiment 1
Air bag nitrogen water shutoff groove of the present utility model includes a tank 1, the crown center of tank 1 is connected with an end of a gas pipeline 2, the other end of gas pipeline 2 and air bag 3 connect, and also are provided with an intake ducting 4 on gas pipeline 2, and intake ducting 4 is provided with a manually-operated gate 5.
If after the said apparatus installation, when treating the high liquid level of tank 1, open manually-operated gate 5, will replenish nitrogen injection air bags 3 by intake ducting 4, close manually-operated gate 5; When liquid level in the tank 1 descended, nitrogen entered in the tank 1 by gas pipeline 2 from air bag 3; When liquid level in the tank 1 rose, nitrogen entered in the air bag 3 by gas pipeline 2 from tank 1.When liquid level changes in the tank 1, nitrogen circulates between air bag 3 and tank 1, realize the nitrogen envelope of tank 1, but nitrogen can be because of not being discharged into air loss, if nitrogen small loss in the air bag 3, can regularly open manually-operated gate 5 and replenish nitrogen, thereby can realize to reduce greatly the consumption of nitrogen, save working cost.
Embodiment 2
In like manner, gas pipeline 2 also can be arranged on the air bag 3 or top of tank 1, does not give unnecessary details one by one at this.
Claims (5)
1, a kind of air bag nitrogen water shutoff groove, it includes a tank, it is characterized in that it also includes one for the air bag that holds nitrogen, a gas pipeline that can this tank and this air bag be connected for the intake ducting that replenishes nitrogen and, this intake ducting is provided with a valve.
2, air bag nitrogen water shutoff groove according to claim 1 is characterized in that this intake ducting is arranged on this gas pipeline.
3, air bag nitrogen water shutoff groove according to claim 1 is characterized in that this intake ducting is arranged on this sink top.
